Meeting the Sultan Hamengkubuwono X Every year, Tatiek's family has a family tradition to go to her grandfather's house in Soronatan, Yogyakarta. Her grandfather was a retired palace official. In the late 1960s, Tatiek met the oldest son of the late reigning Sultan
Hamengkubuwono IX, Herjuno Darpito, who, later on, succeeded his father as Sultan
Hamengkubuwono X. At the age of 19 Hemas was married to
Herjuno Darpito (6 years older) and left her study in the university. Her name was changed for the first time as Bandara Raden Ayu Mangkubumi, before finally being changed to Gusti Kanjeng Ratu Hemas when
Herjuno Darpito ascended the throne and became Sri Sultan
Hamengkubuwono X. She had five daughters;
Princess Mangkubumi, Princess Candrakirana,
Princess Maduretno,
Princess Hayu, and
